Note: Restoring tests from a floppy disk, USB storage device, or network file server will erase all test
and patient database information on the hard disk and will replace it with the information from the
source. Data from the USB storage device, network file server, or backup floppy disks may be
merged onto the hard drive to add tests that do not exist on the hard drive. See
“Merging
Databases,” on page 11-22 .
WARNING: Every patient has an identifier that consists of Name, Date of Birth, Patient
ID, and Issuer of ID. To avoid unintentional automatic merging of patient records,
VERIFY a unique combination of Name, Date of Birth, Patient ID, and Issuer of ID
exists when patients are copied, transferred, retrieved from an archive, or restored
from a back up. There is no way to separate the combined records of erroneously
merged patients. Automatic merging of patient records occurs when a patient exists
in the local database with the EXACT SAME Name, Date of Birth, Patient ID, and
Issuer of ID as a patient that is copied, transferred, retrieved from an archive, or
restored from a back up.
For example, consider the following scenario:
Patient A: This patient is currently on the local HFA database and was automatically
assigned a unique Patient ID by the instrument because it was a blank field prior to a
software upgrade to V5.x software or during an import to the HFA through a copy,
transfer, retrieval from archive, or a restore from backup.
Patient B: This patient is about to be transferred to the local HFA database and has
the same Name and Date of Birth as Patient A, but does not have a Patient ID (i.e.
field is blank). When Patient B is copied, transferred, retrieved from an archive, or
restored from a back up to the local HFA database, Patient B will automatically be
assigned the same Patient ID and Issuer of ID as Patient A, and Patient B will be
merged with Patient A.
Using DATABASE STATUS gives you information on the number of tests and the number of patients
found on the hard disk or on a floppy disk.
The Archive/Retrieve button allows you to manually archive and retrieve. The archiving and retrieval
functions only are available if you have licensed HFA-NET PRO on your HFA II-
i
. For full details of the
Archive/Retrieve functions and how to set them up, please refer to “Archiving Data,” on page I-14 .
For information on manually archiving and retrieving, see “Manually Archiving Data,” on
page 14-21 , and “Manually Retrieving Archived Data,” on page 14-22 .
Retrieving the File Directory
Selecting a particular File Function is only the first step in accomplishing the chosen task. The next
step involves calling up the directory of tests. The directory is a list of tests contained on a specified
storage medium. It is from the directory that you select the test or tests to be included in the
particular File Function.
WARNING: Only remove a USB device when it is not reading or writing data. Wait for
the HFA progress bar to complete and/or the device’s activity light to cease.
Otherwise, you may damage or corrupt data on your USB device.
